Change the thermocoupling, a 10 minute job. You will get one in most hardware shops .

If this is using a thermopile , its 750 mv or 3/4 of 1 volt and self powered via the pilot flames impingement upon the thermopiles end, the unit may use a thermocouple, they are the same thing in theory however the thermocouple has but a 30mv electric voltage, which is very small either way. Both hold a pilot valve open and the thermopile actually will power the gas valve if a 750 millivolt type system.
I test these 750mv systems by using a AA battery holder from Radio Shack, they come with Positive and Negative leads from the battery and can be used to sipply 1.5 volts. I remove the thermopiles 2 leads and replace the batterys leads with them. If the system works, the thermopile is weak or bad,
